Description

 The present invention relates to a modular autonomous device intended to raise, safely, from the ground level, any inert load at rest intended to be stored in the air and / or to be examined or worked.

 Traditionally, raising a soil load requires the use of very complex and often costly means; means which are often mobile such as, for example, cranes and which require that the load be placed on a firm place in order to release the lifting machine and, with each new operation of displacement of this load, it is necessary to repeat the operation with stowage, slinging, new access of the machine to the site. These operations, for certain materials, are all the more complex that said material is particular in its form, its volume, its weight and often impossible because the configuration of the places which prevent access to the lifting device and / or to its lifting such as, for example in hangars, the height under ceiling which does not allow the necessary deflections; in addition, this type of elevation does not allow the load to have sufficient stability and security to be able to work on it while it is suspended and, when it is placed, there is no longer means of access from below.

 The ~ device according to the invention overcomes these drawbacks and, moreover, to create new possibilities which could not be envisaged by conventional means.

 This device is autonomous and modular. It can include one or more modules depending on the use for which it is intended. Each module; which takes a schematic U-shape, has the function of raising from the ground level, by a vertical movement from bottom to top and vice versa for the descent, any inert load at rest intended to be stored, auscultated or worked.

It consists of two vertical traction masts, fixed on both sides on the base and simultaneously serving both to raise, from ground level, the two carriages which slide from bottom to top in each mast. Each carriage has articulated fasteners supporting adjustable or non-adjustable arms which receive in their end piece, various supports adapted to the load to be lifted.

The base of the device, which is placed on the ground and which is represented by the horizontal part of the U, can be adjustable in the middle to allow the variation of the spacing of the two masts arranged perpendicularly on each of its ends which are, themselves, equipped with longitudinal stabilization crosspieces, each end of which has an assembly and keying system allowing connection with other modules, either upstream or downstream of the masts.

 Elevation height, maneuvering time, power, force, dimensions are determined at construction depending on the service to be provided. The load to be lifted is either placed on one or more individual platforms, or suspended. The areas of use are unlimited for such a device.

 The description referenced in the drawing of Figure 1 shows that the device consists of a steel module (1), in schematic U-shape, the horizontal base (2) is always placed on the ground. This adjustable base at (8) is provided, in each of its ends, with longitudinal stabilizers (9) and (10) themselves having, at each end, a fitting and keying system (11 ) allowing the connection with other devices either upstream or downstream of the masts. At each end of the base (2), are installed perpendicularly two masts (3) and (4) in which simultaneously slide from below and vice versa two carriages (5) on which are mounted two independent arms (6) articulated in azimuth, adjustable in length and able to receive, at their end (7), various supports and fasteners, suitable for the work to be carried out. The carriages are simultaneously raised and lowered by electro-mechanical means.
